Climate change and Global Warming are out of control. This means that, no matter what policies, processes or actions are implemented, the Earth as we know it will never be the same again. There is significant evidence to support this hypothesis. The dilemma becomes whether we can limit the damage and adapt to a new status quo or not. Rising sea levels and the damage caused by this phenomenon has irreversible impacts on coastlines worldwide. Damage to sensitive reef systems cannot be fixed. This also has permanent impacts of the ecology not just of those immediate areas but also the ocean as a whole.
Any discussion of the irreversibility of Climate Change needs to be briefly pre-empted by an explanation of the causes for Climate Change. (Newton G. 2009) ‘Australia's environmental climate change challenge’ states that “Anthropogenic warming of the global climate system is beyond doubt. Impacts from a changing climate are already occurring and the latest scientific research suggests that some aspects are locked in for centuries to come.” If climate change is a man-made phenomenon then it needs to be men (and women) who intervene to minimise the impacts of it on our environment and, eventually, our lifestyles.
Climate Change and Global Warming cause sea levels to rise. This increase in sea levels not only causes inundation of low lying and coastal areas but also irrevocable damage to coastal environments. Globally the ocean is predicted to rise nearly 140 cm on a global scale by the year 2100 (Cooper et al. 2013); therefore this has massive implications for countries all around the world with cities (settlements etc.) based near bodies of water. When compared to the last 80 years this is an acceleration of nearly twice the rate that ...

Leading scientists advise climate change will cause increases to the frequency and intensity of extreme weather events. Rising sea levels pose a significant risk to coastal communities, while the world’s oceans could become too acidic to support coral reefs and other calcifying marine organisms. Coral reefs contain only six per cent of the area of the Great Barrier Reef, yet they provide critical habitat and food for numerous species in the ecosystem. However, climate change has already impacted coral reefs in the Great Barrier Reef as corals are very helpless against its potential impacts. Eight mass coral bleaching events has occurred since 1979, triggered by unusually high water temperatures. And because of this, zooxanthellae (photosynthetic algae) leave their tissues and corals will have no more colours hence ‘bleaching’. Without the zooxanthellae, the corals that remain gradually starve to death. Once the coral dies, fish and a multitude of other marine species are soon affected. Rising sea levels and more frequent and intense storm surges will see more erosion of Australia’s coastline, causing community and residential
The Great Barrier Reef holds some of the most unique colour patterns in the world. But potential threats in the Modern era are having an impact on the Reef and the beauty it holds. The greatest threats are all due to today’s climate change problems. It has been proven that climate change is biggest threat to the reef’s future. Climate Change is having such and impact on the reef because of the rising sea temperatures, ocean acidification and rising sea levels. Look...
One argument is that many different things are contributing to the destruction of coral rather than climate change including overfishing, marine pollution and cyclones/hurricanes (World Climate Report, 2010). Although this may be true, the main causes of coral reef destruction still relates back to global warming. From 1985 to 2012, coral populations in the Great Barrier Reef have decreased by 50.7 per cent, with 48 per cent due to tropical cyclones, 42 per cent because of crown of thorns starfish (COTS) and 10 per cent directly due to bleaching (De 'ath et al., 2012). It has been indicated that due to global warming, there has been an increase in the number of tropical cyclones (Knutson et al., 2010). However, it has also been found that there is a possibility of cyclones actually mitigating coral bleaching (Baker et al., 2008; Schultz, 2012). With even just a 2°C increase in temperature the probability of COTS survival escalates by 240 per cent under certain conditions (Australian Institute of Marine Science, 2015). However, repeated bleaching events result in higher mortality rates. The Caribbean has been experiences continuous declines of reef sites due to repeated bleaching events (Baker et al., 2008). There is no doubt that oceans surrounding Australia have drastically warmed since 1910 (Bureau of Meteorology, 2014), and this warming affects the
Earth, an endless source of wonder and beauty, produced the Great Barrier Reef. Hustling and bustling, the Reef thrives like a busy city, teeming with life. Sheltering thousands, corals, maintain the well-being of the Reef; however, the world threatens its nature and delicacy. Populations growing and technological advances increasing, the world becomes more and more disconnected with the natural world, posing an alarming risk for the planet we live on. Although many organizations try to keep the oceans clean, because of human interference and unnatural occurrences, the Great Barrier Reef needs scientific help to adapt corals to new conditions for means of survival, putting pressure on the Australian government to save their ocean environment.
Coral reefs around the world are in danger. One of the causes is global warming, which has been increasing the temperature of the ocean water resulting in coral bleaching. This essay will focus on damage occurring to the Great Barrier Reef.
The use of fossil fuels has greatly increased the amount of atmospheric and oceanic CO2 to a point where it’s ruining the natural flow of the world; the earth’s temperature is rising. As a result, the polar ice caps are melting causing the seas to rise. With only a 1 meter increase in sea level the United States alone could lose over 10,000 square miles of land, and thousands of houses will be destroyed. The effects will be just as prominent around the world: many islands will become submerged, 17% of Bangladesh will be underwater, and tens of thousands of people will be displaced (“Global Warming” 3).
The Great Barrier Reef is comprised of a series of coral reefs of the coast of the Queensland province of Australia. It is approximately 1,400 miles long, and is the largest living structure on the planet. The reef is among the most diverse regions on our planet, and is home to an astonishing array of animal and plant life. Most of the reef is protected by The Great Barrier Reef Marine Park which was formed in 1975 through the Great Barrier Reef Marine Park Act. However the reef faces a littany of very real threats and dangers. They include climate change, declining water quality from runoff and pollution, extreme weather, coastal development, illegal fishing, and outbreaks of the coral eating crown of thorns starfish.
Surveys of the Great Barrier Reef suggest that more than 90 percent of it has been affected by bleaching. The Great Barrier Reef, known arguably the most iconic, and well known coral reef on the planet is not immune to bleaching. Penis. The problem however is not only in the GBR, it’s stretching as far as the South Pacific to the Caribbean. With the rate of reef bleaching increasing, the toll taken on the ecosystem will increase as well as many fish who rely on getting food at reefs will have to find new hunting grounds. The world's coral reef population is diminishing; they’re dying at an increasing rate and I believe that the installment of artificial reefs, along with raising of awareness will provide significant change.
The Great barrier reef has had many recent hardships, including water pollutants and the increasing water temperature. Although it may be too late to save this particular reef we the people must not be so nearsighted to the
The Great Barrier Reef is located in North East Australia off the coast of Queensland. It is world renowned for its stunning scenery and its flora and fauna diversity, it has also been acknowledged as one of the seven natural wonders of the world. The Great Barrier Reef stretches across 344400km2 and includes thousands of individual reefs and hundreds of islands which are occupied by around 600 types of hard and soft coral, around 1625 varieties of fish, 3000 types of molluscs, more than 30 species of whales and dolphins, just to mention a few components that make up The Great Barrier Reefs vast diversity. In order to preserve and protect the unique array of ecological communities, habitats and species of The Great Barrier Reef for future generations
Oceans cover 71% of the earth’s surface. The talk of climate change can often seem to focus on what is happening in our atmosphere, but there is a lot of change going on in our oceans. The oceans have absorbed 90% of the excess heat and 28% of the carbon pollution generated by human consumption of fossil fuels (Nuccitelli 2015). The purpose of this paper is to show how the effects of climate change effect the coral reefs in our oceans, with a focus on the coral reef systems in the Caribbean and of the Great Barrier Reef. The Caribbean coral reefs are well known to have suffered more damage between the two reef systems. That’s not to say that the Great Barrier Reef has not suffered its own damage. It has and will continue to suffer in the future.
The Great Barrier Reef is said to be the jewel of Australia. However Australian lifestyles have had a significant impact on the reef since European settlers first arrived. This essay will discuss two of the major problems the reef is subject to, and the strategies in place to secure the reefs future. Australian lifestyles and farming occur predominantly on the coast, which subject’s the reef to large quantities of sediment runoff. In addition to this problem is the outbreak of the crown of thorn starfish. However, significant efforts are being made to address these problems. Equally important is climate change and the threat it has on the reef in coming years. Consequently, the Government and other organizations have been looking at ways to increase the reef's resilience, to better cope with this problem. On the whole, much is being done to benefit the reef. However, with the increasing threat of climate change, there is still a great deal that needs to be done to secure the reefs future.
Imagine living along a bright and sunny beach where there are tourists coming and going every day to enjoy the ocean waves and the wonderful sand. Many years later you come to realize that the sandy beach is submerged underwater with no sign of tourists and a possibility of that water flooding into your home. Although this scenario is quite the stretch, it results in the concept of sea level encroachment. One may consider what may be the cause of the rise in sea level? The concluding answer itself is us human beings, more specifically the term “Anthropocene.” The Anthropocene is ultimately how human actions cause such negative influence and damage to our environment leading to global climate change. Through evidence from multiple articles we
One of the major effects of global warming is the rise of sea level due to thermal expansion of the ocean, in addition to the melting of land ice. Now there are dozens of land areas that sit well below sea level and the majority of those land areas are very well populated. At least 40 percent of the world 's population lives within 62 miles of the ocean, putting millions of lives and billions of dollars ' worth of property and infrastructure at risk. (Juliet Christian-Smith, 2011) This means if the sea level rises to the projected level of 25 meters (82 feet) half of the world will retreat back to the ocean. (Rohrer, 2007) Also rising sea levels means higher tides and storm surges riding on ever-higher seas which are more dangerous to people and coastal inf...
